Superficially similar to G. hakeoides which has leaves with two grooves only (either on the lower surface or almost lateral), and markedly rugose fruits with a thin wall c. 0.5 mm thick (0.6–3 mm thick in G. acacioides ). Grevillea brachystachya also has some similarity, but has much more robust and larger flowers (pistils 12–17 mm long) with hairs on the outer surface of the perianth.
